To make a long story short, I have a Technics SL-23 semi auto tabl that works just fine however, my wife want to be able to play LP's but has nerve damage in her arm that does not allow her to carfully move the arm to the right position to lower the arm to the record. So, I found a fully auto table so all she has to do is hit the switch. I want to replace the existing cartridge wuth an Audio Technica AT440 MLa but cant figure out how to remove the headshell. I guess I should have thought about this before I bought a Dual. With Technics it is just screw on, screw off. It doesn't appear that the Dual has that option. I can not locate an owners manual anywhere on the net.

Anyone have any options or opinions to offer.

Thanks in advance.
